A year has passed since the Shuttle launch in Florida, a year during which Saskia has decided that she prefers to be Saskia rather than Richie. As her friend and companion Saskia Hunt leaves school for the last time, Voice arranges for Saskia to exist as an actual person. For the last time (or so he thinks) Richie changes to be Saskia. Now the girls can live together as sisters together forever - and that word has a particular meaning for the pair of them. As the Supertwins, the girls continue to use their powers to help and protect others, including saving most of the world again by actually making a volcano erupt. Having left school (at least one of them has), the girls go to work for James Robinson. Their experiences are decidedly NOT those of your average school-leaver, and their involvement with the security forces comes in handy from time to time. James has cause to be grateful when a helicopter crash is averted by Saskia learning to fly it in a matter of seconds. What they come to call the Saskia Magic helps them help others to come to terms with themselves, including an American businessman who ignores his teenage daughter in favour of his work. Saskia Hunt enjoys being shot at, so foiling a terrorist hijack of a trainload of nuclear fuel sees her with a huge grin as the machinegun bullets bounce off her. Saskia can already drive a car (and other things), she learned the normal way while she was still Richie. Saskia Hunt learns in just a minute or so as Saskia shows her how it's done.
